ADC3643EVM: ADC model used

Part Number: ADC3643EVM
Other Parts Discussed in Thread: ADC3644, ADC3643


According to the schematics of ADC3643EVM board (, ADC3644 is used.

I can't find the datasheet for such ADC.  Is this ADC3644 the actual component mounted on the board?

If so, can you please provide the datasheet?



  • Hi Miguel,

    Apologies for the confusion. The ADC3644 family (pin to pin compatible) contains different speed grades (like the ADC3643 at 65 MSPS), and is the head part for the family. Please rest assured that the ADC3643 IC is placed on the PCB. All parts in this family share the same evaluation PCB, and the next revision of this schematic has the correct part number called out on the schematic.

    The ADC3644 is not yet released (late this year), but is very similar to the released ADC3664 (primary difference being the ADC3644 will have a CMOS data interface).

    Please reach out to me at if you have any further questions about the ADC3644.

    Best Regards,


  • Hi Dan,

    Thanks for your answer.  Everything clear!
